Title: Improvements in or relating to the trimming of a heel end portion of a sole to facilitate the fitting of a heel to a shoe including the sole
IPC: A43D8/34
Filed: 1938-02-02
Abstract: 510,533. Heel-seat fitting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HAZELTON, G. Feb. 2, 1938, No. 3198. [Class 17 (i)] Relates to machines of the kind described in Specifications 421,882 and 482,287 for bevelling the heel-end portion of a sole for snug reception in a tapering groove extending transversely of a heel at the upper end of the breast, and consists in a power operated machine wherein the length of the bevel formed on the sole is substantially the same for soles of differing thickness. A frame 27 pivoted at 41, is provided with arcuate guides 31 for a knife slide carrier 25. A knife 21 is adjustably secured to a slide 23 carrying a roll 119 engaging a slot in a slide 113 reciprocated by a link 125, the end of which, remote from the slide is adjustable along a slot in a link 133, itself pivoted to a cam operated slide 137 and a guide link 135 pivoted to the frame. A work support 11, of the kind described in the prior Specifications, co-operates with a heel end gauge 17 connected to a heel measuring gauge of the kind described in Specification 306,192, [Class 17 (i)]. A member 19, of wedge section longitudinally of the shoe, separates the end of the sole from the shoe, and is formed with a groove 189, the rear edge of which serves as a shear edge. A pair of rolls 39 are adjustably secured to the knife carrying slide, and are urged downwardly by springs 161, stop screws 165 determining their normal lowest position. The carrier 25 is engaged by a pin 65 on a lever 63, pivoted at 61 to the frame 27 and linked to the jack-actuating treadle described in the prior Specification. The lever carries a boss at its pivot presenting a sharply curved surface 98 and a slightly curved surface 99 which co-operate with complementary surfaces 101, 106 on a member fixed to the frame. Normally, the frame 27, which swings about the pivot 41 through a small angle determined by stop screws 29, 55, is at the clockwise extremity of its movement, and the carrier 25 is raised, allowing ample room for the insertion of the shoe. The surface 99 is, then, in contact with the surface 101. After the insertion of a shoe the treadle is depressed and the shoe is urged up against the plate 19 by the jack. Simultaneously, the link 73 rises, swinging the frame 27 upwards until the surface 99 leaves the surface 101, from which point the pin 65 swings the carrier 25 downwardly until the rolls 39 press on the sole. A one revolution clutch is then engaged, with the result that the knife 21 makes its cut, and returns. As the arcuate guides 31 are substantially concentric with the groove 189, the length of the cut within the sole is substantially independent of the thickness of the sole. In a modification, the machine is simplified by omitting the frame 27 and pivoting the knife carrier positively about the axis of the groove 189.

Title: A device for averaging a variable function
IPC: G06G7/186
Filed: 1961-01-31
Abstract: 924,403. Electric analogue calculating systems. ZELLWEGER Ltd. FACTORIES FOR APPARATUS & MACHINES USTER. Jan. 31, 1961 [April 8, 1960], No. 3675/61. Class 37. A variable function is averaged by applying an equivalent electrical quantity to an R-C network having a time constant variable in a predetermined manner and arranged to present the mean value of the function as a voltage across the capacitor of the network. The R-C network in its simplest form consists of a variable resistance 12 connected in series with a fixed capacitor 11 across a generator 1 which produces the function U(t) with respect to time t. An electric motor 14 supplied from a network 15 through a switch 16 varies the resistance 12 according to the law dR/dt = 1/C, where C is the capacitance of 11. With this arrangement the voltage across 11 is exactly the mean of the function U(t). A voltage indicator 2 measures this mean value directly and is ideally of infinite resistance. If, however, its resistance is finite a further variable resistance 17 may be connected across the indicator and varied by the motor 14 to give the desired variation of time constant. The resistance 12 may be a potentiometer driven by the motor 14 so that the resistance varies linearly with time but other resistance changes may be used e.g. of a thermal, optical or electronic nature. The time constant may be varied by using a variable capacitor instead of a resistance. Impedance circuits such as a Miller integrator may be used, the time constant in this case being varied by altering the amplification. The resistors or capacitors may be variable in steps instead of continuously. Specification 681,477 is referred to.

Title: Improvements relating to the regularising of the tension of artificial threads during liquid treatments
IPC: D01D10/04
Filed: 1953-02-12
Abstract: <PICT:0729178/IV (a)/1> For regularizing the thread tension while maintaining a minimum tension value in the liquid after-treatment of a group of artificial threads produced from cellulose solutions in a continuous working operation, the diameters of the guide rollers over which the threads pass between successive liquid treatment baths are varied according to the thread tensions resulting from the swelling effect of the individual baths.  If one bath causes a greater longitudinal swelling of the threads than the preceding bath, the next guide roller is made of larger diameter.  If less swelling occurs in the next bath, the following roller may be left with the increased circumference of the preceding roller, since the increased tension thereby entailed does not impair the even travel of the group of threads.  Alternatively, the diameter of the following roller may be reduced.  Where a succession of baths give successively increased swelling, rollers of successively increased diameters may be used. As shown, a group of threads 1 obtained by the viscose process proceeds from a water bath, e.g. at 55 DEG  C., over a roller 2, which may have a diameter of 100 mm., into a desulphurizing bath 3, e.g. at 80 DEG  C.  The strong longitudinal swelling produced in this bath would lead to entanglement of the threads, but this difficulty is overcome by passing them after leaving the bath over a roller 5 of larger diameter than roller 2, e.g. of a diameter of 101 mm.  The threads are then passed through a washing liquid in bath 6, e.g. hot water.  Since this liquid has a smaller swelling effect than the alkaline liquid of the desulphurizing bath, the diameter of roller 7 may be kept at 101 mm. or restored to 100 mm.  A cold alkaline bleaching liquid in bath 8 produces a strong longitudinal swelling effect, and to compensate for this the diameter of roller 9 is made larger than that of roller 7, e.g. 101 mm.  The group of threads may then be passed through further treatment baths, the diameters of the guide rollers between the baths being adjusted according to the swelling action of the various liquids.  The guide rollers 4, which keep the threads immersed in the liquids as they travel through the treatment baths, are driven by the travelling threads.

Abstract: 114,189. Imray, O., (Soc. of Chemical Industry in Basle). March 20, 1917. Hydrazone dyes, metal compounds of. Watersoluble copper, chromium, and other metal compounds of hydrazone dyes are obtained by treating with copper or copper compounds, chromium oxide or salts, or other metal or metal compound (such as nickel, cobalt, iron, aluminium, cerium. vanadium, or uranium) the hydrazone dyes produced by condensing oxyarylhydrazines, arylhydrazine carboxylic acids, or oxyarylhydrazine carboxylic acids, with aldehydes of the benzene, naphthalene, or furfurol series, or ketones or diketones of the aromatic series. The metal compounds may also be made by producing the parent dye in the presence of the metal or metal salt. The chromium compounds may also be made by first boiling the parent hydrazine with a chromium salt solution to produce a chromium compound of the hydrazine, then condensing this with the aldehyde or ketone to produce a " halfchrome " compound, and finally treating this with a chromium salt to yield the fully-chromed body. Examples are given of the preparation of the parent dyes and the copper and chromium compounds. The properties are tabulated of the copper and chromium compounds of the dyes prepared from the following pairs of components : 1 - oxy - 2 - phenylhydrazine - 4 - sulphonic acid and resorcinyl aldehyde, salicyl aldehyde, 2 : 4 - dinitrobenzaldehyde, #-oxynaphthaldehyde, 2 : 7 - dioxynaphthaldehyde, furfurol, benzil, isatin, thionaphthenequinone, 1 : 2 : 4 - naphthoquinone sulphonic acid, phenanthrenequinone, or acenaphthenequinone ; 1 - oxy - 2 -- phenylhydrazine - 4 - sulpho - 6 - carboxylic acid and furfurol, thionaphthenequinone, 1: 2: 4 - naphthoquinone sulphonic acid, phenanthrenequinone, or acenaphthenequinone; 3 - oxy - 2 - naphthylhydrazine - 6 - sulphonic acid and acenaphthenequinone. The products dye wool in acid baths; the dyeings of such products as contain a carboxyl group in the hydrazine component, or a hydroxyl and a carboxyl group in the aldehyde or ketone component, may be afterchromed.

Abstract: 1,208,064. Electro-photographic process. RANK XEROX Ltd. Jan.26, 1968 [Jan.27, 1967], No. 4118/68. Heading G2H. An electrophotographic plate, comprising a supported softenable layer (e.g. of plastics) having particulate material therein or thereon, has an electrostatic charge image formed thereon and is softened by heat or solvent vapour so that the particulate material migrates to the support, and is further softened by heat and/or solvent vapour to cause agglomeration of the particulate material in non-image areas to reduce the background. If the particulate material is photo-conductive, the charge image is formed by uniform charging (e.g. with a corona discharge) and imagewise exposure, and, if non-photo conductive, by imagewise exposure to a corona discharge using a mask or shaped electrode. The support may be conductive, e.g. metallic, or non-conductive. The softenable layer may be e.g. a rosin ester, alkyd resin, silicone or epoxy resin, polyolefin or polystyrene. The photo-conductive material may be inorganic, e.g. selenium, zinc oxide, or organic e.g. a dye pigment. Typical solvents are the vapours of chloroform, ethyl ether, xylene, dioxane, or benzene. The heating steps may be performed using a hot plate, heating coil or forced hot air, and the exposure to solvent vapours by holding the image plate above the liquid solvent in a graduated cylinder.
